    • Captura i emmagatzemament del dioxid de carboni 

      Bardaji Solanellas, Xavier (Universitat Politècnica de Catalunya, 2012)
      UPC Master thesis
      Restricted access - author's decision
      La captació i l'emmagatzemament de diòxid de carboni (CO2) (CEC) constitueixen un procés que consisteix en la separació del CO2 emes per la industria i les fonts relacionades amb l'energia, el seu transport a un lloc on ...

    • Carbon dioxide capture: a performance analysis of spray towers 

      Toala Escobar, Kimberly Yorllet (Universitat Politècnica de Catalunya, 2023-09-06)
      Master thesis
      Open Access
      Covenantee:   Kungliga Tekniska högskolan
      En els últims temps, les emissions de gasos d'efecte d'hivernacle, emanades de la indústria, han accentuat el fenomen de l'escalfament global, específicament generades per les emissions de diòxid de carboni. Per a reduir ...

    • Diffusion-reaction modelling of the degradation of oil-well cement exposed to carbonated brine 

      Martínez Estévez, Ariadna; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (2017)
      Conference report
      Open Access
      The essential aspects of a diffusion-reaction model in development for the degradation process of oil-well cement exposed to carbonated brine are presented in this paper. The formulation consists of two main diffusion/reaction ...

    • Feasibility study on CO2 capture and storage in silicate substrates 

      Rodriguez Rausis, Kwon Bok (Universitat Politècnica de Catalunya, 2016-07)
      Master thesis (pre-Bologna period)
      Open Access
      The increasing CO2 concentrations in the atmosphere are attributed to the rising consumption of fossil fuels for energy generation. Mineral carbonation technologies methods are needed to prevent the global warming bellow ...

    • Induced seismicity in geologic carbon storage 

      Vilarrasa Riaño, Víctor; Carrera Ramírez, Jesús; Olivella Pastallé, Sebastià; Rutqvist, Jonny; Laloui, Lyesse (2019-06)
      Article
      Open Access
      Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock ...

    • Insights into the direct carbonation of activated lizardite: the identification a poorly reactive amorphous Mg-rich silicate phase 

      Rodriguez Rausis, Kwon Bok; Cwik, Agnieszka Lucyna; Casanova Hormaechea, Ignasi (John Gale, 2020-09)
      Article
      Open Access
      This work aims to shed light on the yet unanswered question regarding the limited carbonation yield of activatedlizardite via direct carbonation. Two amorphous Mg-rich silicate phases were identified upon activation. A ...

    • Modelling acid attack of oilwell cement exposed to carbonated brine 

      Liaudat, Joaquín; Martínez Estévez, Ariadna; López Garello, Carlos María; Carol, Ignacio (John Gale, 2018-01)
      Article
      Open Access
      A diffusion-reaction model for the carbonation process of oilwell cement exposed to carbonated brine under CO2 geological storage conditions is presented. The formulation consists of two main diffusion/reaction field ...

    • Modelling acid attack of oilwell cement exposed to carbonated brine: effect of specimen geometry on experimental results 

      Barandiarán Villegas, Lucía Belén; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (2019)
      Conference report
      Open Access
      In recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oilwell cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil ...

    • Phase evolution during accelerated CO2 mineralization of brucite under concentrated CO2 and simulated flue gas conditions 

      Rodriguez Rausis, Kwon Bok; Cwik, Agnieszka Lucyna; Casanova Hormaechea, Ignasi (Elsevier, 2020-04)
      Article
      Open Access
      Experimental work on the carbonation of brucite has been carried out in the temperature and pressure ranges of 50-120 °C and 1-10 bar respectively, using concentrated CO2 and simulated flue gas. At 120 °C hydro- magnesite ...

    • Techno-economic and exergetic assessment of an oxy-fuel power plant fueled by syngas produced by chemical looping CO2 and H2O dissociation 

      Uddin, Azhar; Bose, Archishman; Ferrero, Domenico; Llorca Piqué, Jordi; Santarelli, Massimo (2018-10-01)
      Article
      Open Access
      Natural Gas Combined Cycle (NGCC) is presently the most efficient fossil fuel power plant but with no carbon capture. The efficiency penalty resulting from the integration of carbon capture and storage (CCS) is, however, ...

    • Zero-thickness interface model with chemical degradation by acid attack 

      Martínez Estévez, Ariadna; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (2019)
      Conference report
      Open Access
      Carbon dioxide (CO2) storage in abandoned oil/gas reservoirs is considered a viable alternative to reduce greenhouse gas emissions to the atmosphere. An important element of the risk associated with long-term CO2 storage ...
